Abstract

Physically Unclonable Functions~(PUFs) have been a potent choice for enabling low-cost, secure communication. However, the state-of-the-art strong PUFs generate single-bit response. So, we propose PUF-COTE: a high throughput architecture based on linear feedback shift register and a strong PUF as the ``base''-PUF. At the same time, we obfuscate the challenges to the ``base''-PUF of the final construction. We experimentally evaluate the quality of the construction by implementing it on Artix 7 FPGAs. We evaluate the statistical quality of the responses~(using NIST SP800-92 test suit and standard PUF metrics: uniformity, uniqueness, reliability, strict avalanche criterion, ML-based modelling), which is a crucial factor for cryptographic applications.
